Lincoln's Inn, London

Lincoln's Inn is the oldest of London's four remaining Inns of Court - areas where those in the legal profession have traditionally lived and worked (the others are Gray's Inn, Middle Temple and Inner Temple). Lincoln's Inn offers many architectural delights and surprises, such as a striking gatehouse, a 17th century chapel and a lovely little garden which features a tool shed in the shape of a castle. Only the garden and chapel are regularly open to the public. The 15th century Old Hall, which plays a role in Dickens' novel Bleak House, is the most antique part of the complex, but access to it is by appointment only.
